Unit Explanations
Candle (International)cd
Source UnitThe candle (symbol: cd) is a unit of luminous intensity in the International System of Units (SI), defined based on the electromagnetic spectrum. Specifically, it represents the amount of light emitted by a source in a particular direction. The modern definition is based on a specific light source, namely, a blackbody radiator at a temperature of 2042 K. This unit allows for the quantification of light output in a manner that is consistent and reproducible, making it crucial for various scientific and industrial applications. It is essential in providing a standard for measuring light intensity, which can vary significantly depending on the source and environmental conditions.
Current Use
Today, the candle is primarily used in fields related to photometry and lighting design, where accurate measurement of luminous intensity and brightness is essential. In the entertainment industry, for instance, it assists in designing stage lighting and visual effects, ensuring that lighting professionals can achieve the desired atmospheric effects. The candle is also crucial in scientific research, particularly in studies involving optical properties and the behavior of light in different materials. Countries worldwide, including the United States and members of the European Union, utilize the candle for standardization in lighting products, ensuring compliance with safety and performance standards. Furthermore, it plays a vital role in the manufacturing of lighting fixtures, where precision in light output is necessary for energy efficiency and consumer satisfaction.
Fun Fact
The candle was first standardized in 1909 by an international agreement.
Decimal Candledc
Target UnitThe decimal candle is a unit of luminous intensity that expresses the brightness of a light source as perceived by the human eye. It is defined as the luminous intensity of a source emitting monochromatic radiation of frequency 540 terahertz and having a radiant intensity of 1/683 watt per steradian. This unit is employed in photometry and is related to other units like the candela, which is the SI base unit for luminous intensity. The decimal candle provides a practical means to quantify and compare the brightness of various light sources in a way that aligns closely with human visual perception, making it essential in lighting design, photography, and other applications where light quality is critical.
Current Use
The decimal candle is widely used in various industries including photography, theater, and architectural lighting design. Photographers use it to gauge the brightness of lighting setups, ensuring proper exposure and color balance in images. In the theater, it helps stage designers to create the desired ambiance and effect through precise lighting. Architects utilize the decimal candle in developing spaces with optimal lighting conditions for both aesthetics and functionality. Additionally, it finds application in research and development within the field of optics, where accurate assessment of light intensity can influence product design and innovations. Countries such as the United States, Germany, and Japan have embraced it in their lighting standards and practices.
Fun Fact
The decimal candle was developed to improve upon earlier, less precise units of light measurement.

It is essential in providing a standard for measuring light intensity, which can vary significantly depending on the source and environmental conditions.
History & Origin
The origin of the candle as a unit of measurement dates back to the early use of candles in various cultures. Originally, candles were made from tallow or beeswax and served as a primary source of light in homes and public spaces. The need for a standard measure of light output became evident as technology advanced and the use of electric lighting became widespread. In the late 19th century, various attempts were made to standardize luminosity, but it wasn't until 1909 that the 'international candle' was formally defined. This definition was crucial, as it marked a transition from a historical artifact to a scientifically grounded unit of measurement.
Etymology: The word 'candle' derives from the Latin 'candela', which means 'to shine'. This etymology reflects the candle's role as a source of light, capturing its essence in illumination.
